[Chronic subdural hematoma as a cause for blindness].

The uncommon complication of bilateral blindness resulting from a decompressive neurosurgical procedure is presented by the case of a 51-year old patient suffering from a traumatic chronic subdural haematoma. A breakdown of the altered vasoregulation of the optic nerves due to papilledema at the time of intracranial pressure drop is supposed to be the etiological background of optic atrophy and consequent amaurosis. The causal relationship of accident trauma and blindness in the presented case is pointed out.
